Someone is polling negative messaging about both Mayor de Blasio and his Republican challenger Staten Island Assemblywoman Nicole Malliotakis.

Someone is polling negative messaging — from afternoon naps to Trump ties — about both Mayor de Blasio and his Republican challenger Staten Island Assemblywoman Nicole Malliotakis, the Daily News has learned.

A source shared audio of the poll, conducted by Mountain West Research Group, with the News. The source was called Monday, and no candidates or independent spenders in the race have so far reported paying the company.

The poll first offered positive summaries about each candidate. In introducing de Blasio, the pollster cited rent freezes, a minimum wage hike, and a plan to create 100,000 new jobs paying at least $50,000.

“According to the Daily News, his initiatives have generated $21 billion in direct benefits to the city’s residents,” the pollster read, before asking for an opinion of the mayor.

The pollster then introduced Malliotakis as “the daughter of Greek and Cuban immigrants,” Staten Island’s first Hispanic elected official, someone who was “fearless in taking on politics as usual” and believed the mayor had been presiding over “runaway spending” and an increase in sex crimes, all frequent Malliotakis talking points.

After asking for whom the caller would vote, the poll quickly segued to more negative commentary about each candidate, asking the voter to rate how concerned the statement made them.

For Malliotakis, the pollster said she’d “supported the Trump administration assault on immigrant populations in New York City” and suggested President Trump was right to withhold funds from sanctuary cities. In another, the pollster said Malliotakis endorsed Trump’s campaign for president and quoted her as saying they had a “common vision” on some issues.

Malliotakis had endorsed Marco Rubio; she never officially endorsed Trump but did vote for him.

It’s unclear who might have placed the poll in the field.

The pollster also asked for reactions to statements about her vote against a minimum wage hike, against banning outside income for Albany lawmakers, and her opposition to President Obama’s Affordable Care Act.

In testing negative messages about de Blasio, the pollster read a statement saying the city needed a “full-time mayor” and noting de Blasio’s focus on national issues and his trip to Germany after a Bronx cop was murdered.

“He spends hours at the gym in the morning and takes naps in his office in the afternoon,” the pollster said.

A second statement said de Blasio ran on a tale of two cities but that his administration had continued to approve new luxury condos while “thousands of dollars in campaign contributions pour in from big developers.” A third noted the “no fewer than five separate inquiries” into de Blasio for “potential wrongdoing.”

“The de Blasio administration even allowed a corrupt real estate developer and de Blasio donor to make millions in profits by converting a nursing home into luxury condos in May of last year,” the pollster read, a reference to the Rivington House debacle.

It’s unclear which candidate — if any — might have placed the poll in the field. Candidates will sometimes poll negative messages against both their opponents and themselves to determine which lines of attack work on their foes and where they themselves are most vulnerable. A third-party running an independent expenditure may also use such a poll to test messaging.

Malliotakis’ campaign shows expenditures to just one pollster, Buffalo-based Barry Zeplowitz & Associates. The de Blasio campaign’s expenditures show payments to Greenberg Quinlan Rosner, home to Anna Greenberg, who has been de Blasio’s pollster for several years.
